TAIVlPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 793,433, dated June 27, 1905.

Application filed January 11, 1904. Serial No. 188,507.

To all ill/1.0m, it may concern:

Be it known that I, HENRY GEISENHONER, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvementsin Tamping-Machines, of which the following is a specifica tion.

Thisinvention relates to machines for tamping or ramming earth, and it is especially intended for use on road ways and along railwaytracks where the earth or other filling material needs to be solidly tamped under and around the ties or in other locations.

The invention comprises a truck furnished with a motor for propelling it, either an electric motor or asteam or gas engine, as desired. The truck carries a vertically-movable frame, in which is journaled a horizontal shaft transverse to the truck and geared for rotation to a motor mounted on the frame. The shaft is provided with a plurality of cranks or their equivalent, each of which is operatively connected with one or more rammers or tamping devices, preferably levers, suitably supported by the movable frame and equipped with proper tamping-tools. Means are provided for traversing the frame transversely of the truck, so as to cause the several tamping devices to operate on all parts of the road bed. The propelling-motor, the tamping-motor, and the mechanism for raising and lowering the movable frame and for traversing it are controlled from the platform of the truck.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a tamping-machine embodying my improvements. Fig. 2 is a top plan view of the same with the controlling works removed. Fig. 3 isatransverse section on the line 3 3, Fig. 2. Fig. 4 is a side elevation of a modification, and Fig. 5 is a side elevation of the mechanism for traversing the movable frame.

The truck is composed of suitable side frames 1, united by end beams 2, and having pedestals to receive the axles 3 of the wheels 4. If the machine is to run on a track, these are ordinary flanged car-wheels, as shown. One or both axles may be positively by a suitable motor. In Figs. 1, 2, and 3the propelling device is an electric motor 5, geared to one of the axles in the ordinary manner; but if a source of electric current is not available the truck may be driven by a steam or gas engine 6, as shown in Fig. 4, connections with an axle being made by sprocket-wheels 7 and chain-belt 8. In each side frame of the truck is an upright slot whose parallel sides form ways to receive and guide a frame 9, in the upper part of which is journaled a horizontal shaft 10, extending across the truck and provided with a spur-gear lLmeshing with adriving-pinion 12, secured on the shaft of an electric or other motor 13, which is supported on a movable frame 14, pivotally suspended from the shaft 10. At each end of the shaft 10 and at intermediate points are cranks 15, each of which is connected by a rod 16 with a lever 17, fulcrumed on a bar 18, which is secured in the lower part of the movable frame 14 and extends each way therefrom in the plane of the shaft 10. There are preferably two rods connected to each crank, actuating two levers placed side by side on the bar 18, but diverging downwardly, so as to straddle a railroad-tie 19. At the lower end of each lever is a tampiug-tool 20. The shaft 10 and the bar 18 can slide lengthwise in their bearings in the frames 9, so that the tamping-tools can be made to operate on the roadway material along the entire length of the tie, the travel of the shaft being greater than the space between adjacent tools. The longitudinal movement of these parts is obtained by any suitable mechanism, preferably that shown in the drawings, where the movable frame 14 is provided with a rack 21, meshing with a gear-wheel 22, secured on a short shaft journaled in bearings in the lower end of a hanger 23, depending from a bolt 24, secured in an upright slot in a standard 26, fastened to the floor 27 of the truck. On the shaft is a smaller gear-wheel or pinion 28, which meshes with a segment-rack 29 on the lower end of a lever 30, fulcrumed on the bolt 24, and having a latch 31 cooperating with a toothed quadrant 32, carried by the hanger driven l 23. The lever moves in the plane of the rack which is parallel with that of the shaft 10 and bar 18, so. that when the lever is operated it causes the gear-wheels to move the rack in a direction transverse to the length of the truck, and thus slides the shaft and the bar lengthwise in their bearings.

In order to enable the tamping-tools to work at different depths, the side frames 9 are vertically movable in their slots. I prefer to raise and lower them by means of chains 33,

whose lower ends are fastened to the frames 9 and whose upper ends are secured to a transverse shaft 34, provided with a hand-wheel 35 for winding the chains up or down. A ratchet and pawl 36 hold the frames and tam ping-tools at any desired height.

The lever for traversing the tools, the wheel for raising and lowering them, the controller 37 for the motor, and the brake-wheel 38 for operating the brakes 39 are all grouped conveniently for manipulation by the operator, who stands on the floor of the truck near one end thereof, the trolley-stand 40 being at the other end. He is thus enabled to move the truck along the track, adjust the tampingtools to a tie, and cause them to operate upon the tamping material along the entire length of the tie and at such depths as may be necessary to secure a firm packing of the material under and around the tie.

When the movable side frames are moved vertically, the bolt 24 must be loosened to permit it to slide in the slot 25 in the standard 26, the bolt being tightened again after the tamping-tools have been adjusted to the proper height.

When a gas or steam engine 6 is used to propel the truck, it can also be utilized to drive the tamping-tools, as by means of a belt 41 and a sprocket-wheel 42 on the shaft 10.

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. A machine for operating upon road-beds, comprising a truck, a vertically-movable transverse shaft thereon, a motor for driving said shaft, and levers actuated by said shaft.

2. A machine for operating upon road-beds, comprising a truck, a vertically-movable transverse crank-shaft thereon, a motor for driving said shaft, and levers connected with said crank.
